Can't change non-I/O font size in schematic entry

ipsbiz · ‎12-16-2008

I upgraded to WebPack 13.1 (was using 11.4 for a specific existing design, the files of which were "upgraded" by 13.1 to work with it). I now seem to have a font size setting issue. Existing net names (non-I/O either on or at the end of a wire net) come up at 16 pt. text. The existing I/O net names come up at 28 pt. When I set the non-I/O net names to 28 pt., they change to 28 pt. (and look larger on the screen). However, when I save, close the schematic and then reopen it, the non-I/O net names I thought I had changed revert back to 16 pt. text. I changed a non-I/O net to an I/O and it behaved as expected (font size -> 28 pt.). When I changed it back to non-I/O, it went back to 16 pt. I tested the I/O net names and was able to change the font size, save close and reopen the schematic and the I/O net name remained at the changed font size. This seems like it should be a simple and straightforward action. Is there something I'm missing here? Is there some default font size I can set for non-I/O net names? Thanks and cheers....Steph

I have exactly the same problem - rather confusing with large schematics (Win7, 64b, ISE 13.1).

I found out that the error is probably in missing "fontsize" attribute in .sch xml-format file for branches.

E.g.

may be changed to

with correct fontsize (now 28) and fontname (now Arial) after .sch file reopen.

So it seems that the SED-like command line find&replace tools can provisionally help after each save schematic:

find: <attrtext style="alignment:

replace: <attrtext style="fontsize:28;fontname:Arial;alignment:

(mind the quotation mark problem in command line)

Wow...3 years and someone else finally runs into this same problem. Are we the only ones? Or is it that no one else has come across it, or maybe they have and it doesn't matter to them? This is something that should not have to have a bandaid work around. This never used to to be an issue. Thanks for your efforts and suggestion. I will look into using it as a temp solution. Cheers....

Hi! I'm searching for a long time for font size change solution in Schematic editor of ISE Webpack. I still not found anything useful. I'm use Linux. The qt4config app only let me change interface font, but i need to increase symbol's pin names. I can't tolerate with extremely small pin name font size. This pervent me of using ISE and i'm stuck in legal Foundation 4.2i, it is last version i have which has good support for fonts size change. So i unfortunately can't use Spartan-3 devices as Foundation 4.2i never support it. So my designs even in year 2011 still limited to Spartan-2. Please help me to increase all fonts in Schematic editor. (Please do not suggest use screen magnifiers or other strange solutions). I still need real solution, and it is so simple and easy to realize for softeare developers. Thanks!
